Abstract
A one-piece closure for dispensing product from a container has a cap secured to the container and a lid connected to the cap by a support arm through an integrally molded hinge. The support arm is pivoted by the hinge between a pair of upstanding projections on the end wall of the cap. Ribs projecting laterally from the support arm engage the projections to maintain the lid opened when the container is inverted to dispense product. When the lid is pushed closed, the ribs deform to allow the support arm to pass between the projections. In one embodiment, side edges of the ribs engage upwardly facing cylindrical camming surfaces on the projections. In another embodiment, the outer surfaces of the ribs engage confronting flat surfaces on the two projections. In the closed position of the lid, the ribs in both embodiments are received in recesses in the projections so that they do not become permanently deformed and loose their effectiveness over time.
